In case you haven't found out yet, Apple Watch it has Bluetooth, NFC and Wi-Fi technologies implemented to be able to communicate with iPhones or payment instruments compatible with Apple Pay, and this gives it better connectivity than that of other smartwatches. Although many believed that The Apple Watch will only interface with iPhones via Bluetooth, the reality is that the main method of interaction will be a Wi-Fi network, if the devices are both connected to the same hotspot. In this situation, the transfer of music, photos, etc., will be done much faster than via Bluetooth, Apple most likely using the AirDrop system to facilitate this communication.
Unlike Bluetooth, Wi-Fi has a much larger range, so it allows the use of a Apple Watch connected to an iPhone located even a few tens of meters away. Moreover, in the case of connected accessories to listen to music, it will not be necessary to approach them to play whatever we want to listen to, everything can be done from a distance without effort. Of course, the Apple Watch will have to be connected to a Wi-Fi network and if we don't do this using its screen, then we will do it with the help of the companion application for iPhone.
